GIVEN IN THIS VOLUME IS A SELF-CONTAINED SET OF COMPUTER PROGRAMS WHICH CAN BE USED TO ANALYZE THE BEHAVIOR OF AN EMBANKMENT CONSTRUCTED ON SOFT SOIL. THE INDIVIDUAL ROUTINES, CONSISTING OF THE MAIN PROGRAMS SAND AND DETR AND 24 SUB-ROUTINES, ARE WRITTEN IN FORTRAN IV. COMPLETE LISTINGS ARE GIVEN FOR ALL PROGRAMS, AND DETAILED FLOW DIAGRAMS ARE PROVIDED FOR THE AMIN PROGRAMS. BASED ON CONSIDERATIONS INVOLVING THE CONCOLIDATION PROCESS AND THE STABILITY OF THE EMBANKMENT-SUBSOIL SYSTEMS, PROGRAM SAND DETERMINES THE TIMES AT WHICH NEW LOAD INCREMENTS CAN BE APPLIED; THE CRITERIA DEPEND ON WHETHER A SPECIFIED PORTION OF THE ULTIMATE CONSOLIDATION SETTLEMENT UNDER A REFERENCE LOAD AND/OR A SPECIFIED FACTOR OF SAFETY IS OBTAINED AT THE TIME OF A NEW LOAD APPLICATION. IF THE LOAD INCREMENTS AND THE TIMES OF LOAD APPLICATION ARE PROVIDED AS INPUT, THE PROGRAM CAN ALSO BE USED TO ANALYZE THE CONSOLIDATION PROCESS AND THE TIME-DEPENDENCY OF SETTLEMENTS WITHOUT PERFORMING A STABILITY ANALYSES. PROGRAM DETR CALCULATES THE REQUIRED SPACING OF VERTICAL SAND DRAINS BY CHECKING WHETHER A SPECIFIED SMOUNT OF SETTLEMENT AND/OR A SPECIFIED FACTOR OF SAFETY IS ASSURED AT A SPECIFIED TIME. ALTHOUGH PROGRAM SAND CAN HANDLE VARIABLE COEFFICIENTS OF CONSOLID- ATION., PROGRAM DETR REQUIRES THAT THESE COEFFICIENTS BE CONSTANT.
